报道一种胡柚鲜果的保鲜贮藏方法,即:成熟后采摘的鲜果在1.0% CaCl2溶液浸泡20分钟后,用透明的保鲜膜包裹1层,在贮藏4个月后,鲜果外观较完好、无明显菌斑。鲜果在0.01% KMnO4溶液中

摘要本研究报道一种胡柚鲜果的保鲜贮藏方法,即:成熟后采摘的鲜果在1.0% CaCl2溶液浸泡20分钟后,用透明的保鲜膜包裹1层,在贮藏4个月后,鲜果外观较完好、无明显菌斑。鲜果在0.01% KMnO4溶液中浸泡20分钟后,用透明的保鲜膜包裹1层,在贮藏6个月后,外观完好、无明显菌斑。鲜果在0.15 g/L水杨酸溶液中浸泡20分钟后,用透明的保鲜膜包裹1层,贮藏5个月后,外观完好、无明显菌斑。鲜果在1.0% CaCl2+0.01% KMnO4溶液,或者0.01% KMnO4+0.15 g/L水杨酸溶液,或者1.0% CaCl2+0.01% KMnO4+0.15 g/L水杨酸溶液中浸泡20分钟后,再用透明的保鲜膜包裹1层,在贮藏8个月后,外观较完好、无明显菌斑。本方法适宜胡柚鲜果的长期贮藏。71038

Abstract The storage method of Citrus changshan fruit was produced in the study. Fresh fruit picking after maturity treated with 1.0% CaCl2 solution soak for 20 minutes, wrapped with transparent preservative film a layer, and stored after 4 months, fruits’ appearance were intact, no significant bacterial plaque. Fresh fruit in the 0.01% KMnO4 solution soak for 20 minutes, with transparent preservative film wrap a layer, and after 6 months, appearance were intact, no obvious plaque. Fresh fruit in 0.15 g / L salicylic acid solution for 20 minutes, with transparent preservative film a layer, after 5 months, appearance were intact and no obvious plaque. Fresh fruit in 1.0% CaCl2 and 0.01% KMnO4 solution, or 0.01% KMnO4 and 0.15 g / L salicylic acid solution, or 1.0% CaCl2, 0.01% KMnO4 and 0.15 g / L salicylic acid solution for 20 minutes, with transparent preservative film wrap a layer, and after 8 months, the appearance were relatively intact, no significant plaque. This methods are suitable for long-term storage of Citrus changshan fruit.
